Page 1 of 3 ADDITIVE, DIESEL CORROSION INHIBITOR WSS-M99C133-A1 1. SCOPE The material defined by this specification is

2、a fuel corrosion inhibitor additive. 2. APPLICATION This specification was released originally for materials used as an initial fill diesel fuel corrosion inhibitor additive to provide increased protection against corrosion of injectors (nozzle hole) from acidic condensate (from exhaust gases) gener

3、ated during frequent key on/offs and vehicles being shunted around in the vehicle plants and at conversion companies (eg. Camper vans). This fuel additive is intended to be blended into the initial fill fuel at vehicle plants (where needed) using an inline injection equipment. 3. REQUIREMENTS 3.1 AP

4、PROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available

5、externally through a Ford Materials Engineer. 3.2 PHYSICAL/CHEMICAL PROPERTIES Dodecenyl succinic anhydride (DDSA) has been proven to be an effective organic corrosion inhibitor and is used in multifunctional fuel additive packs worldwide as well as a pipeline corrosion inhibitor in some markets. DD

6、SA shall be sourced in a 50/50 solution with a standard aromatic solvent in the diesel boiling range (eg. Aromatic 150). Properties below are defined for the liquid mix of DDSA into an aromatic solvent. A treat rate of 200 ppm for the total add pack (100 ppm active DDSA concentration) has been teste

7、d and proven to be effective at the time of the release of this specification. 3.2.1 Density at 15 C 950 kg / m3 max (ASTM D7042, EN ISO 3675) 3.2.2 Viscosity at 40 C 2.0 cSt max (ASTM D445) 3.2.3 Pour Point 5 C max (ISO 3016) 3.2.4 Flash point 55C min (ASTM D93, EN ISO 2719) ENGINEERING MATERIAL SP

8、ECIFICATION WSS-M99C133-A1 Copyright 2018, Ford Global Technologies, Inc. Page 2 of 3 3.3 PERFORMANCE When added to initial fill diesel (eg. diesel fuel compliant with Ford spec WSS-M4C126-A1), the additive must meet the performance criteria set below, and must have no harmful effect on the engine a

9、nd vehicle fuel system and no adverse effect on engine exhaust emissions. 3.3.1 Rust Prevention A max (NACE TM0172) 3.3.2 Rust Prevention A max (ASTM D665-B, Proc B) 3.3.3 Ford vehicle test (Obtain full test procedure from Ford Fuels In the morning, start the vehicle from ambient Run engine at 1500

10、rpm no load and monitor engine coolant temperature When coolant temperature is the hotter of either; o 5 C above coolant at the start of the test, or o 5 C hotter than “EGR activation temperature” Turn off the vehicle After 2 weeks (10 days), remove the injectors and return to the component engineer

11、s Injector to then be forwarded to the FIE supplier to assess for nozzle flow-only measurement, microscopic analysis of the spray holes and nozzle body for corrosion. Note - Testing must be performed at the recommended treat rate. 3.4 HOUSEKEEPING Frequent checks must be performed on the initial fil

12、l diesel in the fuel storage tank(s) at the plants implementing blending of this additive in order to ensure that it is free of alkali and alkaline metals (Na, K, Ca, Mg) and also no significant amount of free water accumulates at the bottom of the tank/ near the pick-up point (water bottoms need to

13、 be properly managed by maintenance teams). 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications. 4.1 VERIFICATION The affected Material

14、s Engineering activity reserves the right to conduct verification testing. If the test results do not support the originally submitted data, the supplier must re-test the product in coordination with the affected Materials Engineering activity. This re-test must be conducted and certified by a mutua

15、lly agreed upon test facility. 4.2 FLAMMABILITY This material represents a potential fire hazard. The Manufacturing Engineering Department or other responsible activity shall notify both the Security and Safety Units of its presence to assure that proper fire precautions are provided. The location i

16、n which it is used or stored shall be included in the notifications. ENGINEERING MATERIAL SPECIFICATION WSS-M99C133-A1 Copyright 2018, Ford Global Technologies, Inc. Page 3 of 3 4.3 SAMPLING AND SUBMISSION OF SAMPLES (ISO 3170/3171, ASTM D 4057/D 4177) Quality Control records must be made available

17、to Fuels and Lubricants Engineering upon request. 4.4 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their labor

18、atory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification. Tested material samples must be available for review upon request and kept for a minimum of one year. Upon request, the

19、 supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.5 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the material upon which approval was originally

20、granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification requirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing, and Materials Engineering activities of t
